RD-12 and RD-13 moved both ActionState consumers into their machines. This
left ActionState with zero users, so this ticket deletes it outright.
SaveState is different. It has two four-way consumers (brief.page.ts and
org-template.page.ts) that still switch on all four cases, so it survives.
It moves into debounced-save.ts, next to createDebouncedSave, the only
function that sets it. Both store imports merge into the existing
debounced-save import line. The doc comments that named ActionState are
reworded, since the type no longer exists. No store's public saveState
signature changes, so brief/ui/ needs no edit.
This completes the phase. Two encodings survive: RemoteData for fetched
data, and each machine's own state union. SaveState stays as an explicitly
justified third encoding, for a separate concern (debounced autosave status)
that the other two do not cover.
